结构弹塑性分析可以较好地反映结构的薄弱部位。大震弹塑性分析和小震设计、中大震拟静力分析具有一定的可比性。如图是YJK的拟静力楼板应力分析结果及ABAQUS大震分析的损伤结果，弹塑性分析反映了结构的薄弱部位。

ABAQUS 做整体分析比较花时间，计算也需要花很多时间，因此，每个过程均需要十分细心，因为错了从来时间成本太大。 不管是前处理建模，还是后处理分析，还有超限文本撰写，都应该是建立在对结构理解的基础上，不能论文一个操作员，能简化，能提高效率的地方就要提高效率，尽量把更多时间用在把握和理解结构机理、结构特性、建立结构概念基础上。
Abaqus云图网格显示控制。有限元分析结果通过云图可以很酷炫的展示出来，很多时候，在云图中取隐藏单元的网格可以更加酷炫。在Abaqus中可以通过设置 Common Plot Option来控制对象的显示方式，如下图所示。崔济东, www.jdcui.com, by Ji Dong Cui
